We are counting down the days until May 31st when Google Australia kicks off Google's global Developer Day - that's right, we're the very first of ten Google offices around the world hosting this huge event.

Due to the size of the response from the Australian community, we have moved the event to the larger Australian Technology Park which means we'll be able to host all those who waitlisted (thank you for your patience) as well as those who were lucky enough to get in early.

Registration of delegates kicks off at 8.30am. Australian Engineering Director, Alan Noble presents his welcome keynote at 9.15am. Make sure you get in early to secure a good seat.

We'll have many great speakers on the day, including one of the Google Maps creators, Lars Rasmussen, talking about the Google Web Toolkit, Google APIs and why Open Source code plays an important role at Google.

Maps API tech lead Bo Majewski will lead an interactive session that teaches people how to build and optimise their maps mashups.

James Macgill, lead developer on the Open Source Java code library GeoTools prior to joining Google, will take you through an innovative approach to making all those maps mashups more discoverable by our millions of Australian users and hundreds of millions of global users.

There'll be heaps of other activities and opportunities to chat with Googlers and other developers. Check out the sessions page for more details.

The Australian Technology Park is easy to reach from central Sydney or the airport and there is an entrance to the heritage-listed facility directly from platform 10 at Redfern station. If you're coming from outside of Sydney, be sure to get your hotel booked asap.An attendance confirmation e-mail was recently sent out to those that had registered and been waitlisted. It is important that we get your "yes" response to this email as we may open up unconfirmed spots to those who missed making the waitlist.
